Small Scale Military Headquarters

Anyone know what the deal is with the 2 BCA exclusive BBI mustangs (Hurry Home Honey and Cripes A Mighty)??? I've been keeping an eye on ebay for them and haven't seen them show up for a while now. Have they become "rare" or something?

I need a "Cripes" also. I have HHH. I do like the BBI P-51s and no I haven't seen them listed for some time.
